Les sondes et sabots à diffraction en temps de vol génèrent des ondes longitudinales de diffraction dans l'acier. Elles sont utilisées dans des applications de dimensionnement des fissures à l'aide de la technique de diffraction en temps de vol (TOFD).
Our time-of-flight diffraction transducers are highly damped longitudinal wave probes that offer excellent resolution in challenging TOFD applications. These highly sensitive composite element broadband transducers are available in frequencies from 2.25 MHz to 15 MHz and in sizes from 3 mm (0.25") to 12 mm (0.50"). They are for use with specialized TOFD wedges designed to produce refracted longitudinal waves in steel.
